Campylopodiella contains four species in the world. One species is known from Asia.

Gametophytically, Campylopodiella is very similar to Brothera, especially in the cross section of costa. Takaki (1973) separated the two genera based on their setae. He described Brothera as having curved setae and Campyopodiella as having erect ones. Frahm (1984) disagreed with this distinction because he discoverd that the setae of Campylopodiella are also flexuose as those of Brothera, although they are not typically curved. He further suggested that the difference of calyptrae between the two genera is not constant. Thus, Frahm (1984) concluded that the two closely related genera are mainly differentiated by the width of the costa.
